cold intake id wonder who drove this car and was it racedabused or not check if the tranny is not noisy drive in all gears accelerating and decelerating listen for the dif noise it should not whine the engine should run smooth watch out if the bottom part of the oil dipstick is covered with dark deposits poor maintenance check the oil level when going from deceleration to acceleration there shouldnt be too much lash in the drive train test the ac and other options especially the roof mechanism
